The paleolithic diet (abbreviated paleo diet paleodiet), also popularly referred to as the caveman diet, Stone Age diet and hunter-gatherer diet, is a modern nutritional plan based on the presumed ancient diet of wild plants and animals that various hominid species habitually consumed during the Paleolithic era—a period of about 2.5 million years which ended around 10,000 years ago with the development of agriculture and grain-based diets. In common usage, such terms as the "Paleolithic diet" also refer to the actual ancestral human diet

Some of the pseudogenes are transcribed and even translated. And no one has any idea what is their function. Beat that.
